Ah yes.. They do indeed bring back many fond memories! I still have 3 of the 4 original Estes models, Like Fishhead I also lost my sprint on a C6-7 but several years ago. I now also have 3 of the four in Micro-Maxx downscale size only one missing...you guessed it the Sprint, which is on the micro build list for this summer.
Great to see them in a group
Got a few of my oldies together for a picture... In 1979 I got my first Red Max kit I loved it and did a pretty poor job buildind it (no sealer, brush painted and half the decals destroyed during application). From then on every few years I built another one as good as my modelling skills at the time would permit me. In the picture attached the models are from 1979, 1985, 1989 and 2000.
Boy, what to do next!
